When heated, some may melt, and when cooled, some may crumble. Knowing the optimal temperature for producing plastics can ensure the strongest and most durable products. Differential Scanning Calorimetry is a precise analytical tool that examines and measures the performance and degradation of polymers when exposed to a wide range of temperatures. The thermal stability of a sample in the presence of oxygen can also be examined using a DSC device. In this study, a brief description of the DSC thermal test is given, followed by a review of the Oxidation Induction Time\/Temperature (OIT) test.     <br\/>Keywords: Differential Scanning Calorimetry (DSC) test, Oxidation Induction Time (OIT) test.<\/p>\n\n<h2 class=\"wp-block-heading\">Introduction<\/h2>\n\n<p class=\"wp-block-paragraph\">Differential scanning calorimetry (DSC) is a method used to study the response of polymers to heating. DSC testing can be used to investigate the melting behavior of a crystalline polymer or the glass transition. <\/p>\n\n<p class=\"wp-block-paragraph\">The DSC setup consists of a measuring chamber and a computer. Two measuring plates, one containing the sample under investigation and the other used as a reference (and usually empty), are heated in the DSC. The computer monitors the temperature changes and adjusts the rate of temperature change of the DSC plates.  <\/p>\n\n<p class=\"wp-block-paragraph\">The rate of temperature change for a given amount of heat is different between the two chambers of a DSC apparatus. This difference depends on the composition of the contents inside the chambers as well as the physical changes that occur, such as phase changes. In the DSC method, the system changes the heat supplied to one of the chambers to keep the temperature of both chambers the same. Finally, the difference in heat consumed to keep the temperature of the two chambers the same is reported and a graph of heat difference (q) is plotted against temperature (T). Figure 1 shows the internal schematic of a DSC apparatus.    <\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1.png\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Figure 1. General diagram of a DSC device<\/figcaption><\/figure>\n\n<p class=\"wp-block-paragraph\">The thermal properties of polymers obtained using the DSC diagram are:<\/p>\n\n<h3 class=\"wp-block-heading\">1-Heat capacity (Cp):<\/h3>\n\n<p class=\"wp-block-paragraph\">The heat capacity of a substance is the amount of heat required to raise its temperature by 1\u00b0C. Cp is usually reported in J\/\u00b0C and can be obtained by dividing the heat flow by the heating rate. The heat flow is the amount of heat supplied per unit time:<br\/>Relationship 1:  <br\/><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-1.png\" srcset=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-1.png 624w, https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-1-300x33.png 300w, https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-1-260x28.png 260w, https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-1-50x5.png 50w, https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-1-150x16.png 150w\" alt=\"\" width=\"624\" height=\"68\"\/><br\/>Where in Equation 1, t is equal to time. Also, the heating rate is equal to the rate of change of temperature over time:<br\/>Relationship 2: <br\/><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-2.png\" srcset=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-2.png 624w, https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-2-300x30.png 300w, https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-2-260x26.png 260w, https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-2-50x5.png 50w, https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-2-150x15.png 150w\" alt=\"\" width=\"624\" height=\"63\"\/><\/p>\n\n<p class=\"wp-block-paragraph\">Which in equation 2, T\u2206, is equivalent to the temperature change. Finally, the heat capacity is obtained by dividing these two equations:<br\/>Relationship 3: <\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-1-3.png\" alt=\"\"\/><\/figure>\n\n<p class=\"wp-block-paragraph\">If the Cp of a material is constant over a temperature range, the graph of heating rate versus temperature will be a line with a slope of zero, as shown in Figure 2. In this case, if the heating rate is constant, the distance between the fixed line and the x-axis will be equal to the heat capacity. Otherwise, the heat capacity is obtained from the slope of the graph of heating rate versus temperature.  <\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-2.png\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Figure 2. Temperature-dependent flow diagram for a material whose Cp does not change during heating. <\/figcaption><\/figure>\n\n<h3 class=\"wp-block-heading\">2-Glass transition:<\/h3>\n\n<p class=\"wp-block-paragraph\">When a polymer cools from its molten state, it reaches its glass transition temperature (Tg) at some point. At this point, the mechanical properties of the polymer change from that of an elastic material to that of a brittle material due to the change in chain mobility. Figure (3) shows the heat flow diagram as a function of temperature at the glass transition temperature. The heat capacity of polymers is different before and after the glass transition temperature. The heat capacity (Cp) of polymers is usually higher than their Tg. DSC is a valuable method for determining the Tg of polymers. It is noteworthy that the glass transition does not occur suddenly at a specific temperature but rather over a range of temperatures. The middle temperature of the sloping region in the diagram is considered as the Tg.      <\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-3.png\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Figure 3. Glass transition schematics. The glass transition results in a kink in the heat versus temperature diagram due to a change in heat capacity (A). In the heat flow versus temperature diagram, it is a gradual transition that occurs over a range of temperatures (B). The glass transition temperature is considered to be in the middle of the sloping region.      <\/figcaption><\/figure>\n\n<h3 class=\"wp-block-heading\">3-Crystalline:<\/h3>\n\n<p class=\"wp-block-paragraph\">Above the glass transition temperature, the polymer chains are highly mobile. At temperatures above Tg, the chains have sufficient energy to form an ordered arrangement and crystallize. Crystallization is an exothermic process and therefore heat is released to the surroundings, hence less heat is required to keep the sample and reference temperatures the same, resulting in a decrease in the recorded heat flow and a drop in the flow versus temperature graph as shown in Figure (4).  <br\/>The crystallization peak can be used to confirm the occurrence of crystallization in the sample, and it can also be used to determine the crystallization temperature (Tc) and the latent heat of crystallization. The crystallization temperature is defined as the lowest point on the graph. The latent heat (enthalpy) of crystallization is calculated from the area under the curve.  <\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-4.png\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Figure 4. Example of a crystallization peak in a heat flow versus temperature graph. Crystallization is an exothermic process, so the heat flow to the sample must be reduced to maintain a constant heating rate.  <\/figcaption><\/figure>\n\n<h3 class=\"wp-block-heading\">4- Melting:<\/h3>\n\n<p class=\"wp-block-paragraph\">At the melting temperature, the polymer chains are free to move. Melting is an endothermic process and requires the absorption of heat. The temperature remains constant during the melting process, despite continued heating. The energy added during this time is used to melt the crystalline regions and does not affect the average kinetic energy of the chains that have already melted.   <br\/>As can be seen in Figure (5), this appears as a jump and discontinuity in the heat versus temperature diagram. The heat that enters the system during the melting process is the latent heat of fusion and is calculated from the area under the melting peak in the heat flow versus temperature diagram. The melting temperature (Tm) is the temperature at the highest point of the melting peak. After the melting process, the temperature increases again with heating. However, the heat capacity of a polymer in the molten state is higher than that of a solid crystalline polymer. This means that the temperature increases at a slower rate than before.     <\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-5.png\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Figure 5.

An example of a heat flow versus temperature diagram for a polymer undergoing a glass transition, crystallization, and melting. <\/figcaption><\/figure>\n\n<p class=\"wp-block-paragraph\">It is worth noting that not all polymers undergo all three transitions during heating. The crystallization and melting peaks are observed only in polymers that are capable of crystallizing. This is because 100% amorphous polymers only show the glass transition peak. Since semi-crystalline polymers usually also contain amorphous regions, they also show the glass transition peak. Figure (7) shows a comparison between the DSC plot of a semi-crystalline polymer and an amorphous polymer.    <\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-7.png\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Figure 7. DSC diagram of a semi-crystalline polymer and an amorphous polymer <\/figcaption><\/figure>\n\n<p class=\"wp-block-paragraph\">In addition to the information mentioned, using a DSC device, an oxidation induction time test is performed to examine the oxidation performance of a material under heat:<\/p>\n\n<h2 class=\"wp-block-heading\">Oxidation induction time\/oxidation induction temperature<\/h2>\n\n<p class=\"wp-block-paragraph\">Metals are subject to corrosion, while plastics are resistant to corrosion but degrade in environments containing oxygen, heat, and light. Polymer manufacturers use stabilizers to improve the stability of polymers against oxidation. For example, polyethylene decomposes at 200\u00b0C, while in the absence of oxygen and in a nitrogen atmosphere, it decomposes thermally at 400\u00b0C. To improve stability against thermal decomposition, antioxidants are added to the polymer.  <br\/>The degree of resistance to oxidation and environmental factors depends on the application of the polymeric materials. A simple method for evaluating the effectiveness of a stabilizer is to determine the oxidation induction time or oxidation induction temperature (OIT*\/OIT) of the molten polymeric materials. Therefore, it is important to estimate the maximum time and temperature at which they exhibit oxidation stability.  <br\/>OIT is a standard DSC test. OIT*\/OIT measurement is considered for polymer quality control as a method to evaluate the performance of stabilizers, especially in polyolefins. <\/p>\n\n<h2 class=\"wp-block-heading\">Introduction<\/h2>\n\n<p class=\"wp-block-paragraph\">The oxidation induction temperature and time test is one of the qualitative tests in the evaluation of PE pipes. This test rapidly oxidizes the sample, and is used to evaluate whether the reaction is endothermic or exothermic. The OIT test is performed in two ways: oxidation induction temperature and oxidation induction time, each of which will be briefly explained below.   <\/p>\n\n<h2 class=\"wp-block-heading\">Oxidation induction time (Dynamic-OIT)<\/h2>\n\n<p class=\"wp-block-paragraph\">In this regard, the polymer sample (approximately 15 mg) is placed in a clean aluminum container, and the measurement is performed after placing the uncovered sample container together with an empty reference container in a calibrated DSC apparatus under nitrogen gas. According to the EN728T standard, the nitrogen and oxygen gas flow must be adjusted to 50 ml.min-1 during all measurement steps. The sample and reference are heated at a rate of at least 20 K\/min to the temperature at which the OIT value is determined. When the required temperature is first reached, they are placed in an isothermal step for 3 minutes. After reaching this point (t1), the atmosphere is changed to oxygen and the DSC oven is kept at the same temperature until an exothermic signal (oxidation) is detected. The onset of this oxidation signal is related to the time t2 (the values \u200b\u200bof t1 and t2 are shown in Figure 8). However, often the signal is detected to be lower than that shown in the figure, so it is not easy to determine the onset temperature. In this case, it is difficult to evaluate t2, because there is a deviation from the baseline as time t2. Finding the right measurement temperature for the isothermal phase is often difficult in OIT measurements; if the temperature is too low, the measurement time increases significantly. On the other hand, if the temperature is too high, oxidation occurs immediately after the introduction of oxygen and the temperature t2 cannot be determined. In this test for polyolefins, a time range of 30 to 60 minutes and a temperature of 200 to 210 \u00b0C are often suggested. <\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-8.png\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Figure 8. OIT test according to ISO 11357-6 (2002) <\/figcaption><\/figure>\n\n<h2 class=\"wp-block-heading\">Oxidation Induction Temperature (Static-OIT*)<\/h2>\n\n<p class=\"wp-block-paragraph\">*OIT is the point in the thermogram where oxidation (Onset) begins. *OIT is usually expressed as the start time t2 in the test. As shown in Figure 9, in this case, the sample is heated continuously (110\u00b0C\/min) in the presence of oxygen gas (or air). In this method, it is not necessary to change the gas at a defined time.  <br\/>Comparing the relevant points, it is obvious that the OIT* method requires fewer adjustments and provides a better starting point.<\/p>\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/behinpolymerco.com\/wp-content\/uploads\/2023\/09\/thermal-9.png\" alt=\"\"\/><figcaption class=\"wp-element-caption\">Figure 9. OIT test* <\/figcaption><\/figure>\n\n<h2 class=\"wp-block-heading\">Conclusion:<\/h2>\n\n<p class=\"wp-block-paragraph\">Differential scanning calorimetry (DSC) is a powerful method for identifying the physical and chemical structure of materials and is considered a thermal analysis. Differential scanning calorimetry is used to quantitatively measure energy changes. This method can be used to measure melting temperature, latent heat of fusion, glass transition temperature, and crystallization temperature. Also, considering the above, it can be concluded that the OIT thermal stability test is an important factor in determining the performance of polymer materials and parts when exposed to high temperatures. This test is used to examine raw materials and also to examine the quality of the final product. If the OIT value of the raw materials is low, it indicates low thermal resistance and the materials cannot be processed; or there is a possibility that the materials will lose their stability and be destroyed during processing.    <\/p>\n\n<p class=\"wp-block-paragraph\">Compiled by: Marzieh Shams Harandi, Samin Saleki<\/p>\n\n<h3 class=\"wp-block-heading\">Resources<\/h3>\n\n<p class=\"wp-block-paragraph\">1.
